Ati Hd5870 Bios For Mac

August 4, 2010

ATI Radeon HD 5870 includes three video ports: two Mini DisplayPorts and one dual-link DVI port. This allows you to connect the 24-inch Apple LED Cinema Display plus another Mini DisplayPort-based display, and a DVI-based display such as the 30-inch Apple Cinema HD Display. Display adapters are available to connect VGA displays.

5770 and 5870 in MacPro and rom

I used efi rom from new imac’s 5750 and original 5770 pc rom to create custom hybrid rom.

It works in osx, no injector used.

Since I used mobility ATI rom we have nothing from card on boot, but once osx booted – the card works.

Both dvi ports work, displayport works too, 3 displays doesnt work atm.

Once we have macpro’s 5770/5870 roms boot screen should work too. But for now you can already enjoy 5770 in your macpro.

It only works on 2008+ macpros, because efi is 64-bit now, not ebc anymore.

screenshots and the rom:

before flashing you also need to install driver.

Also, 5870 is working too in macpro.

Hi

I recently brought a ATI Radeon with every intention to end up using Three screens,

one display is a 30' Apple Cinema Display and the other two are BenQ GL2450H

The Graphics card has 2x DVI 1x HDMI and 1x Display port.

After reading a few articles on here I purchased a 'active Display port to DVI adapter

I have tried every combination of plugging all three screens with no success with the third Display, although and this is what gets me in the system properties under Graphics and Displays it clear displays that all three Displays are connected. but only two display are working.
